To all whom, it 'may concern:

Be it known that I, ERNEST W. More, a subject of the King of GreatBritain and Ireland, and a resident of London,l England, have inventedcertain new'and useful Improvernents in Calking Apparatus for' Tunnels,of which the following is a specification.

My invention relates more particularlyto the apparatusand attachmentsAfor'calking the joints between the segments of tunnel."-k linings,particularly tunnel-linings of the characterv illustrated and describedin my patent of July 11, 1905, No. 794,635.

It is the object of my invention to provide" an apparatus which can beconvenientlyein# ployed to calk the joints both circumferen-- tially andlongitudinally in a rapid and -eflicient manner.

In the accompanying drawings, Figure `1 is'A a transverse section of atunnel with such an apparatus embodying my improvements; Fig. 2 is aside elevation of the saine with the tunnel-lining in section. Fig.' 3is an' enlarged view of Some details. Fig. 4 is a similar view at rightangles thereto. Figs; 5 and 6 are enlarged views at right angles to eachother, representing a modified form of tooliholder; and Figs. 7 and 8are views of a modified form of tool used with a pneumatic hameReferring to Figs. 1 and 2,7A A are metallic segments which are fittedtogether to form the finished tubular lining of the tunnel. B

B are brackets which are secnredat a suitable height to the flanges ofthe segments of which the iinished lining has: been builtiup. On thesebrackets are mounted rails C C, on which travel the wheels of thestagefD, carrying the calking-tool and the means' for 'operating thesame. The manner of advancing the stage and the arrangement 'of therails' cylinder G3. arm H passes through a suitable yoke I at the end ofthe shaft G such a manner as to permit the arm being-drawn in'and outperthese bearings'. Suitable means are also proengaged by a rack G2,operated by a hydraulic The toolcarrying or revolving pend-icularly tothe shaft in the eventof havi ing to clear obstructions such aspipes,`&c.,' passingalong the tunnel. To do this, Irprefer to provideashaft i, mounted onl the yoke I and having at each end a bevel-gear i,meshing with a corresponding 'gear i2 at the end of each threaded shaft.113. Each shaft i3 passes through suitable. bearings Ion the l yokeand'threaded projections I2 on' the arm H, parallel with the arm.The'shafts irnay have cranks or other operating`.mean's. The

. arm H is provided with a slot H to permit its being raised or loweredvvvithoutinterfering with the shaft G, which passes therethrough. At theend of the arm H is carried the calking-tool and holder, Whichvary inshape for different materials used inv calking as well'as for calkin-gfcircumferential orv longitudinal seams or joints.

In Figsj 3 and 4 is shown'a tool' especially adapted for Kcal'kingcircumferential joints or the seams betweenthe ringsl of tunnel-seg;-

ments. The tool, which is preferably mounted .at the end of therevolving arm, consists ofa hydraulic cylinder J or the like, having 'apiston J., at' ther end of which is attached the The pistontJissubjected to .a constant pressure maintained'at its back through thesupply-pipe A; second pipe y" .is also connected to the cylinder .fortheY liquid to act on the' opposite'si'd'e of. the piston'. Swiveled tofkthe end ofl thev piston-rod isVA the toolV` head K, carrying aloos'elyemounted roller' or wheel K onthefpin 7c order 'that it may havesufficient lateral play to accommodate itself to the: longitudinalvariations of the seams; VThe head may be secured to the piston-rod by apinpassingthrough` one of two holes` at'ri'ghtanglesto each otherinorder to enable' the tool to` do both .circumferential andl'ongitudinaljoints; The'necessar. lonfAV gitudina'l movement may bearranged or by having the arm traverse the "comparatively IOO shortlength of the longitudinal seams. The calking of these longitudinalseams is however, usually done by means of a tool-holder, such as shownin Figs. 5 and 6,which consists of a longitudinal frame M, along whichthe hydraulic cylinder carrying the tool K is caused to travel. Asshown, the frame M is provided with two threaded shafts l M', passingthrough collars J3 on the cylinder. The shafts are geared together atone end, and one of the shafts is provided with a handwheel M2 or othermeans for rotating the same. As this shaft rotates the cylinder iscaused to move along the guideways M4 in the frame. The calking mediummay be round lead wire, which is carried on a spool on the staging D andis led around in front of the roller, so that as the roller advancesVaround the seam it forces the lead into the seam in front of it. Softiron may be preferred to lead on account of its rusting capabilities. lnthe use of iron it may be more desirable to use a pneumatic hammer, suchas illustrated in Figs. 7 and 8. To the head of the hammer is attachedor swiveled a calking-tool best adapted for the work. It is obvious thatthis style of tool may be used with the tool-holder shown in Figs. 5 and6 in calking longitudinal joints, in which case flexible tubes foroperating the hammer should be used.
